Description

本発明は、空気の汚れである微小物を除去するフィルターを備えたレンジフードに関する。 The present invention relates to a range hood provided with a filter that removes minute objects that are dirt in the air.

従来、この種のレンジフードには調理で発生する油煙や埃等を捕集する目的としてフィルターが取り付けられているものが知られている（例えば、特許文献１参照）。 Conventionally, this type of range hood is known to have a filter attached for the purpose of collecting oily smoke, dust, and the like generated during cooking (see, for example, Patent Document 1).

以下、そのレンジフードについて図６を参照しながら説明する。 Hereinafter, the range hood will be described with reference to FIG.

図６は特許文献１に開示されている従来のレンジフード１００の構成図である。油等の汚れを含む空気１０１は、吸込口１０２を通過して排気装置１０３の前方に配置されたフィルター１０４を通過する。センサー１０６がフィルター１０４の汚れを検知すると、駆動装置１０５がフィルター１０４を回転させて、汚れを遠心力で除去する。 FIG. 6 is a configuration diagram of a conventional range hood 100 disclosed in Patent Document 1. As shown in FIG. Air 101 containing dirt such as oil passes through a suction port 102 and passes through a filter 104 disposed in front of the exhaust device 103. When the sensor 106 detects dirt on the filter 104, the driving device 105 rotates the filter 104 to remove the dirt by centrifugal force.

また、この種のレンジフードには調理で発生する油煙や埃等を捕集する目的としてフィルターを取り付け、そこのフィルターを洗浄液に浸漬させて洗浄するものもある（例えば、特許文献２参照）。 Some types of range hoods have a filter attached for the purpose of collecting oily smoke or dust generated by cooking, and the filter is immersed in a cleaning solution for cleaning (see, for example, Patent Document 2).

以下、そのレンジフードについて図７を参照しながら説明する。 Hereinafter, the range hood will be described with reference to FIG.

図７は特許文献２に開示されている他の従来のレンジフード２００の構成図である。 FIG. 7 is a configuration diagram of another conventional range hood 200 disclosed in Patent Document 2. In FIG.

レンジフード２００は、吸込口２０１とファン２０２との間に設けられるフィルター２０３を備える。フィルター２０３は略水平に延びる回転軸２０４で回転できる。フィルター２０３の回転軸２０４より下方の部分が、洗浄タンク２０６に収容された洗浄液２０５に浸漬される。フィルター２０３の回転軸２０４より上方の部分には油、埃等の汚れを含む空気が通過してその汚れが付着している。フィルター２０３を回転軸２０４で回転させることで、汚れが付着した部分を回転軸２０４より下方に位置させて洗浄液２０５に浸漬させて洗浄する。 The range hood 200 includes a filter 203 provided between the suction port 201 and the fan 202. The filter 203 can be rotated by a rotating shaft 204 extending substantially horizontally. A portion below the rotating shaft 204 of the filter 203 is immersed in the cleaning liquid 205 accommodated in the cleaning tank 206. Air including dirt such as oil and dust passes through the portion above the rotating shaft 204 of the filter 203, and the dirt adheres. By rotating the filter 203 with the rotating shaft 204, the portion with dirt attached is positioned below the rotating shaft 204 and immersed in the cleaning liquid 205 for cleaning.

以下、本発明の実施の形態について図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１〜図３に示すように、調理器（図示せず）の上方または周囲に、調理にて発生した油煙や周囲に浮遊する埃である微小物を捕集する吸込口１を設けたフード２を設置し、フード２には、天面に屋外と連通したダクト３を介して連通する吐出口４を設け、内部には排気装置５を包括した送風ケーシング６を配設し、この排気装置５を介し吸込口１と吐出口４を結ぶ通風路７を形成している。また、フード２内の吸込口１近傍には平坦な整流板８が設けられ、吸込口１の下流側となる排気装置５の前面に駆動手段９を連結した油や埃を捕集するための円盤状のフィルター１０を設け、フィルター１０外縁にはフィルター１０を覆い被さる筒形状の洗浄ケーシング１１を有し、フィルター１０前面には、複数の噴射口１２をフィルター１０に対向させ、フィルター中心側１３からフィルター円周端側１４に筒状のノズル１５が設けられている。ノズル１５は、貯水装置１６と給水ポンプ１７に給水パイプ１８ａと給水パイプ１８ｂで接続されて給水手段１９を形成し、ノズル１５は固定具２０により洗浄ケーシング１１に固定されている。また、洗浄ケーシング１１の下端部には小孔２１を設け、洗浄ケーシング１１内に散乱した汚水を小孔２１から排水して回収する回収手段２２を設けている。貯水装置１６には、フィルター１０に固着した油や埃などの汚れを剥がしやすくするため、例えば約４０℃のお湯を洗浄前に入れるが、以下では水と記載して説明する。 (Embodiment 1)
As shown in FIGS. 1-3, the food | hood provided with the suction inlet 1 which collects the microscopic thing which is the smoke generated by cooking, or the dust which floats in the circumference | surroundings above or around a cooker (not shown) 2, the hood 2 is provided with a discharge port 4 that communicates with the outside via a duct 3 that communicates with the outside, and a blower casing 6 that includes an exhaust device 5 is disposed inside the hood 2. A ventilation path 7 connecting the suction port 1 and the discharge port 4 via 5 is formed. In addition, a flat rectifying plate 8 is provided near the suction port 1 in the hood 2, and is used to collect oil and dust having a driving means 9 connected to the front surface of the exhaust device 5 on the downstream side of the suction port 1. A disk-shaped filter 10 is provided, and a cylindrical cleaning casing 11 covering the filter 10 is provided on the outer edge of the filter 10. A plurality of injection ports 12 are opposed to the filter 10 on the front surface of the filter 10, and a filter center side 13 is provided. A cylindrical nozzle 15 is provided on the filter circumferential end side 14. The nozzle 15 is connected to a water storage device 16 and a water supply pump 17 by a water supply pipe 18 a and a water supply pipe 18 b to form a water supply means 19, and the nozzle 15 is fixed to the cleaning casing 11 by a fixture 20. Further, a small hole 21 is provided at the lower end of the cleaning casing 11, and a collecting means 22 is provided for draining and collecting the sewage scattered in the cleaning casing 11 from the small hole 21. In order to easily remove dirt such as oil and dust adhered to the filter 10, for example, hot water of about 40 ° C. is put into the water storage device 16 before washing.

図４に示すように、ノズル１５は樹脂で成形されたものであり、筒状の閉端２４が閉端であり、閉端２４の反対側は開口部２５とし、開口部２５をキャップ２６で塞ぐことで内部が空洞の筒状部材としている。さらに、ノズル１５には前記給水パイプ１８ｂを接続して連通させる給水パイプ接続部２７と複数の噴射口２９が開口した噴射口構成面２８が形成されている。そして、このノズル１５はこの複数の噴射口２９の位置が閉端２４側に向い２９ａ、２９ｂ、２９ｃ、・・と順次位置が高くなるように、前記固定具２０により前記洗浄ケーシング１１に固定されている。 As shown in FIG. 4, the nozzle 15 is molded of resin, the cylindrical closed end 24 is a closed end, the opposite side of the closed end 24 is an opening 25, and the opening 25 is a cap 26. By closing, the inside is a hollow cylindrical member. Further, the nozzle 15 is formed with a water supply pipe connecting portion 27 that connects and communicates with the water supply pipe 18b and an injection port forming surface 28 in which a plurality of injection ports 29 are opened. The nozzle 15 is fixed to the cleaning casing 11 by the fixing tool 20 so that the positions of the plurality of injection ports 29 face the closed end 24 side and the positions of the nozzles 15 become higher in order, 29a, 29b, 29c,. ing.

なお、上記位置が高くなるとは、レンジフードを設置したときの状態で、吸込口１が下、吐出口４が上となる垂直方向の位置関係を示す。 In addition, the said position becoming high shows the positional relationship of the perpendicular direction in which the suction inlet 1 is down and the discharge outlet 4 is up in the state when a range hood is installed.

上記構成において、調理時に発生した油や室内の埃などの汚れは、排気装置５を運転することで整流板８の周囲の吸込口１からフード２内に吸い込まれ、通風路７内に設置したフィルター１０にて捕集・蓄積され、その後、排気装置５によって吐出口４よりダクト３を通じ排出される。 In the above configuration, dirt such as oil and indoor dust generated during cooking is sucked into the hood 2 from the suction port 1 around the rectifying plate 8 by operating the exhaust device 5 and installed in the ventilation path 7. It is collected and accumulated by the filter 10 and then discharged from the discharge port 4 through the duct 3 by the exhaust device 5.

その際、フィルター１０に付着した汚れ、特に埃は、フィルター１０の孔に入り込み複雑に絡み合うことで除去が非常に困難になって油の付着を促進するとともに、しだいに付着が増しフィルター１０の孔を塞いで目詰まりを発生させ、排出風量の低下を招くこととなる。 At that time, dirt adhering to the filter 10, particularly dust, enters the hole of the filter 10 and becomes intricately entangled, thereby making it very difficult to remove the oil and promoting the adhesion of the oil. As a result, clogging occurs and the exhaust air volume is reduced.

そのため、フィルター１０の洗浄を行うが、まず、駆動手段９によりフィルター１０を回転させ、同時に給水ポンプ１７により貯水装置１６に貯めた水をくみ上げノズル１５に供給する。ノズル１５の噴射口１２より勢いよく噴射された水はフィルター１０表面に衝突しながら汚れを剥がし落とすとともに、フィルター１０の孔を通過する際に絡み合い蓄積された埃も合わせて除去し、あわせて回転による遠心力にてフィルター１０から飛散させて洗浄することとなる。 Therefore, the filter 10 is washed. First, the filter 10 is rotated by the driving means 9, and at the same time, the water stored in the water storage device 16 is pumped by the water supply pump 17 and supplied to the nozzle 15. The water jetted from the nozzle 12 of the nozzle 15 peels off the dirt while colliding with the surface of the filter 10, and also removes entangled and accumulated dust when passing through the hole of the filter 10, and rotates together. It will be washed by being scattered from the filter 10 by centrifugal force.

給水ポンプ１７で水が給水開始される当初は、給水ポンプ１７や給水パイプ１８ａ、１８ｂに含まれていた空気が気泡となり、気水混合状態でノズル１５に給水されるが、水は空気よりも重くてノズル１５の内部下部に溜り、気泡に含まれる空気がノズル１５内で水面から空気中に出て行き気水分離され、ノズル１５の閉端２４側に向って順次高くなっている噴射口２９から最初は気水分離された空気が放出されて、その後に水が噴射される。 At the beginning of water supply by the water supply pump 17, the air contained in the water supply pump 17 and the water supply pipes 18a and 18b becomes bubbles and is supplied to the nozzle 15 in a gas-water mixed state. An injection port that is heavy and accumulates in the lower part of the inside of the nozzle 15, and air contained in the bubbles exits from the water surface into the air in the nozzle 15 and is separated into air and water, and is gradually increased toward the closed end 24 side of the nozzle 15. The air which was initially air-water separated is released from 29, and then water is injected.

従って、気泡を含んだ水は噴射口２９から放出されないので、水の噴出ムラによる水滴の飛散や噴出時の異音の発生が低減されるという効果を得ることができ、フィルター１０に給水手段１９から水が噴射されてフィルター１０に付着した汚れを落とし、その汚水は洗浄ケーシング１１の下端部の小孔２１を通って回収手段２２に回収されるので、定期的にフィルターを取り外すことなく、乾燥し固着したフィルターの油や埃などの汚れ、また、洗浄液に浮遊している汚れを手間なく除去できるという効果を有するレンジフードを提供できる。 Accordingly, since water containing bubbles is not discharged from the injection port 29, it is possible to obtain an effect that scattering of water droplets due to uneven ejection of water and generation of abnormal noise at the time of ejection are reduced. Water is sprayed from the filter 10 to remove the dirt adhering to the filter 10, and the dirty water is collected in the collecting means 22 through the small hole 21 at the lower end of the cleaning casing 11, so that it can be dried without periodically removing the filter. Thus, a range hood having the effect of easily removing dirt such as oil and dust on the filter and the dirt floating in the cleaning liquid can be provided.

（実施の形態２）
図５において、図４と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。 (Embodiment 2)
5, the same components as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

図５は、ノズル１５を略水平に設けた状態で、噴射口構成面の長手方向に沿った２列は、上下方向２列として以下説明する。 FIG. 5 will be described below in the state in which the nozzles 15 are provided substantially horizontally, and two rows along the longitudinal direction of the jet nozzle constituting surface are two rows in the vertical direction.

図５に示すように、ノズル１５の噴射口構成面２８には、ノズル１５の閉端２４に向って噴射口３０ａ、３０ｂ、３０ｃ・・を構成する上段噴射口列３０と、ノズル１５の閉端２４に向って噴射口３１ａ、３１ｂ、３１ｃ・・を構成する下段噴射口列３１の２段で構成される複数の噴射口３２が開口している。 As shown in FIG. 5, the upper nozzle array 30 that configures the nozzles 30 a, 30 b, 30 c... Toward the closed end 24 of the nozzle 15, and the nozzle 15 closed A plurality of injection ports 32 constituted by two stages of the lower injection line 31 constituting the injection holes 31a, 31b, 31c,.

噴射口３０ａが構成する上段噴射口列３０はノズル１５の上部、すなわちノズル１５の上部側構成面３３の内壁３３ａに近接するように開口する。下段噴射口列３１のノズル１５の閉端２４側にある噴射口３１ｘと上段噴射口列３０の噴射口３０ａを結ぶ線３４は、下段噴射口列３１の噴射口３１ａと噴射口３１ｘを結ぶ線３５に対して傾きθを形成する。ノズル１５の噴射口構成面２８において、噴射口３１ａが開口している部分の板厚ｔ１、噴射口３１ｘが開口している部分の板厚ｔ２ともに同じとなるように成形する。 The upper jet row 30 formed by the jet ports 30a opens so as to be close to the upper portion of the nozzle 15, that is, the inner wall 33a of the upper side constituting surface 33 of the nozzle 15. A line 34 connecting the injection port 31x on the closed end 24 side of the nozzle 15 of the lower injection port row 31 and the injection port 30a of the upper injection port row 30 is a line connecting the injection port 31a of the lower injection port row 31 and the injection port 31x. An inclination θ is formed with respect to 35. In the injection port constituting surface 28 of the nozzle 15, the thickness t1 of the portion where the injection port 31a is opened and the thickness t2 of the portion where the injection port 31x is opened are formed to be the same.

上記構成において、調理時に発生した油や室内の埃などの汚れは、排気装置５を運転することで整流板８の周囲の吸込口１からフード２内に吸い込まれ、通風路７内に設置したフィルター１０にて捕集・蓄積され、その後、排気装置５によって吐出口４よりダクト３を通じ排出される。その際、フィルター１０に付着した汚れ、特に埃は、フィルター１０の孔に入り込み複雑に絡み合うことで除去が非常に困難になって油の付着を促進するとともに、しだいに付着が増しフィルター１０の孔を塞いで目詰まりを発生させ、排出風量の低下を招くこととなる。 In the above configuration, dirt such as oil and indoor dust generated during cooking is sucked into the hood 2 from the suction port 1 around the rectifying plate 8 by operating the exhaust device 5 and installed in the ventilation path 7. It is collected and accumulated by the filter 10 and then discharged from the discharge port 4 through the duct 3 by the exhaust device 5. At that time, dirt adhering to the filter 10, particularly dust, enters the hole of the filter 10 and becomes intricately entangled, thereby making it very difficult to remove the oil and promoting the adhesion of the oil. As a result, clogging occurs and the exhaust air volume is reduced.

そのため、フィルター１０の洗浄を行うが、まず、駆動手段９によりフィルター１０を回転させ、同時に給水ポンプ１７により貯水装置１６に貯めた水をくみ上げノズル１５に供給する。ノズル１５の噴射口１２より勢いよく噴射された水はフィルター１０表面に衝突しながら汚れを剥がし落とすとともに、フィルター１０の孔を通過する際に絡み合い蓄積された埃も合わせて除去し、あわせて回転による遠心力にてフィルター１０から飛散させて洗浄することとなる。給水ポンプ１７で水が給水開始される当初は、給水ポンプ１７や給水パイプ１８ａ、１８ｂにふくまれていた空気が気泡となり、気水混合状態でノズル１５に給水されるが、水は空気よりも重くてノズル１５の内部下部に溜り、空気は上部側構成面３３の内壁３３ａに近接するように開口した上段噴射口列３０から放出されて気水が分離され、その後に水が噴射されるので、気泡を含んだ状態で発生する水の噴出ムラによる水滴の飛散やそのときの異音が解消されるという効果を得ることができ、フィルター１０に給水手段１９から水が噴射されてフィルター１０に付着した汚れを落とし、その汚水は洗浄ケーシング１１の下端部の小孔２１を通って回収手段２２に回収されるので、定期的にフィルターを取り外すことなく、乾燥し固着したフィルターの油や埃などの汚れ、また、洗浄液に浮遊している汚れを手間なく除去できるという効果を有するレンジフードを提供できる。 Therefore, the filter 10 is washed. First, the filter 10 is rotated by the driving means 9, and at the same time, the water stored in the water storage device 16 is pumped by the water supply pump 17 and supplied to the nozzle 15. The water jetted from the nozzle 12 of the nozzle 15 peels off the dirt while colliding with the surface of the filter 10, and also removes entangled and accumulated dust when passing through the hole of the filter 10 and rotates together. It will be washed by being scattered from the filter 10 by centrifugal force. At the beginning of water supply by the water supply pump 17, the air contained in the water supply pump 17 and the water supply pipes 18a and 18b becomes bubbles and is supplied to the nozzle 15 in a gas-water mixed state. Because it is heavy and accumulates in the lower part of the nozzle 15, air is discharged from the upper injection nozzle row 30 opened so as to be close to the inner wall 33 a of the upper side construction surface 33, and the steam and water are separated, and then water is injected. In addition, it is possible to obtain an effect that water droplets scattered due to water ejection unevenness generated in a state including air bubbles and an abnormal noise at that time are eliminated, and water is sprayed from the water supply means 19 to the filter 10. The adhered dirt is removed, and the sewage is collected in the collecting means 22 through the small hole 21 at the lower end of the cleaning casing 11, so that it is dried and fixed without periodically removing the filter. Stains such as oil and dust Iruta, also possible to provide a range hood that has the effect of dirt floating in the cleaning liquid labor without be removed.

また、上段噴射口列３０と、下段噴射口列３１の２段で構成される複数の噴射口３２においては、下段噴射口列３１のノズル１５の閉端２４側にある噴射口３１ｘと上段噴射口列３０の噴射口３０ａを結ぶ線３４は、下段噴射口列３１の噴射口３１ａと噴射口３１ｘを結ぶ線３５に対して傾きθを形成する。この傾きθ相当の傾斜で閉端２４が高くなるようにノズル１５を前記固定具２０により前記洗浄ケーシング１１に固定する。こうすると、上下２段の噴射口列で構成しても、複数の噴射口３２は、下段噴射口列３１の噴射口３１ａが一番低いところに位置し、下段噴射口列３１が噴射口３１ｂ、３１ｃと閉端２４に向うにつれて徐々に位置が高くなり、噴射口３１ｘの高さは上段噴射口列３０の噴射口３０ａとほぼ同じ位置となり、上段噴射口列３０もまた噴射口３０ｂ、３０ｃと閉端２４に向うにつれて徐々に位置が高くなるので、気泡に含まれる空気がノズル１５の閉端２４側に向って順次高くなっている噴射口２９から順次放出されて気水が分離され、その後に水が噴射されるので、気泡を含んだ状態で発生する水の噴出ムラによる水滴の飛散やそのときの異音が解消されるという効果を得ることができる。 In addition, in the plurality of injection ports 32 constituted by two stages of the upper injection line 30 and the lower injection line 31, the upper injection line 31x and the upper injection line on the closed end 24 side of the nozzle 15 of the lower injection line 31. A line 34 connecting the injection ports 30a of the mouth row 30 forms an inclination θ with respect to a line 35 connecting the injection ports 31a of the lower injection port row 31 and the injection ports 31x. The nozzle 15 is fixed to the cleaning casing 11 by the fixing tool 20 so that the closed end 24 becomes higher at an inclination corresponding to the inclination θ. In this way, even if the upper and lower two-stage injection nozzle arrays are configured, the plurality of injection nozzles 32 are positioned at the lowest position of the injection nozzle 31a of the lower injection nozzle array 31, and the lower injection nozzle array 31 is the injection nozzle 31b. , 31c and the closed end 24, the position gradually increases, the height of the injection port 31x becomes substantially the same position as the injection port 30a of the upper injection port row 30, and the upper injection port row 30 also has the injection ports 30b, 30c. As the position gradually increases toward the closed end 24, the air contained in the bubbles is sequentially discharged from the injection port 29 that is sequentially increased toward the closed end 24 side of the nozzle 15 to separate the steam and water, Since water is jetted after that, it is possible to obtain an effect that dispersion of water droplets due to uneven ejection of water generated in a state including air bubbles and abnormal noise at that time are eliminated.

また、ノズル１５の噴射口構成面２８において、噴射口３１ａが開口している部分の板厚ｔ１、噴射口３１ｘが開口している部分の板厚ｔ２ともに同じとなるように成形すれば、複数の噴射口を同じ径で開口さえすれば噴射口での流体圧力損失は同じであり、複数の噴射口３２から同量の噴射量が得られるノズル１５を簡単に製作することができ、気泡を含んだ状態で発生する水の噴出ムラによる水滴の飛散やそのときの異音が解消されるという効果を得ることができる。 In addition, if the thickness t1 of the portion where the injection port 31a is opened and the thickness t2 of the portion where the injection port 31x is opened are formed to be the same on the injection port constituting surface 28 of the nozzle 15, a plurality of the thicknesses. As long as the nozzles are opened with the same diameter, the fluid pressure loss at the nozzles is the same, and the nozzle 15 that can obtain the same amount of injection from the plurality of nozzles 32 can be easily manufactured, and bubbles can be produced. It is possible to obtain an effect that water droplets scattered due to water ejection unevenness generated in the contained state and abnormal noise at that time are eliminated.

なお、ノズル１５の内筒を形成する金型の抜きテーパと噴射口構成面２８との位置関係を調整し、ｔ１＞ｔ２となるように成形することもできる。こうすれば、噴射口３１ｘが開口している部分の板厚ｔ２が薄いので、複数の噴射口を同じ径で開口さえすれば、噴射口での流体圧力損失は噴射口３０ａから噴射口３０ｘに向かい徐々に少なくなっていく。すなわち、噴射口３０ａから噴射口３０ｘに向かい水の流量が徐々に増える。円盤状のフィルター１０は外周に向うに従い洗浄面が増えるので、噴射口３０ａを円盤状のフィルター中心側１３に対向させ、噴射口３０ｘを円盤状のフィルター１０のフィルター円周端側１４に対向させて配置し、複数の噴射口３２で噴射水量を簡単に調整することができるという効果を得ることができ、気泡を含んだ状態で発生する水の噴出ムラによる水滴の飛散やそのときの異音が解消されるという効果を得ることができる。 It is also possible to adjust the positional relationship between the die taper of the mold forming the inner cylinder of the nozzle 15 and the injection port constituting surface 28 so that t1> t2. By doing this, the thickness t2 of the portion where the injection port 31x is opened is thin, so if a plurality of injection ports are opened with the same diameter, the fluid pressure loss at the injection port is changed from the injection port 30a to the injection port 30x. It gradually decreases in the opposite direction. That is, the flow rate of water gradually increases from the injection port 30a toward the injection port 30x. Since the disk-shaped filter 10 has more cleaning surface as it goes to the outer periphery, the injection port 30a is opposed to the disk-shaped filter center side 13 and the injection port 30x is opposed to the filter circumferential end side 14 of the disk-shaped filter 10. It is possible to obtain an effect that the amount of spray water can be easily adjusted by the plurality of spray ports 32, scattering of water droplets due to uneven ejection of water generated in a state including bubbles, and abnormal noise at that time The effect that is eliminated can be obtained.

なお、本実施例では、ノズル１５と、貯水装置１６と、給水ポンプ１７との位置関係を貯水装置１６、ノズル１５、給水ポンプ１７の順に位置が高くなる事例で説明したが、貯水装置１６、給水ポンプ１７、ノズル１５の順に位置が高くなるような配置し、それぞれを給水パイプ１８ａと給水パイプ１８ｂで接続して給水手段１９を形成した場合には、この複数の噴射口２９の位置が閉端２４側に向い２９ａ、２９ｂ、２９ｃ、・・と順次位置が高くなるようにしてあれば、給水ポンプ１７や給水パイプ１８ａ、１８ｂにふくまれていた空気がすみやかに噴射口２９から放出されるだけでなく、停止した場合には、噴射口２９から逆に空気が入り込み、ノズル１５や給水ポンプ１７や給水パイプ１８ａ、１８ｂの残水が貯水装置１６に還流することはいうまでもない。 In this embodiment, the positional relationship between the nozzle 15, the water storage device 16, and the water supply pump 17 has been described as an example in which the position increases in the order of the water storage device 16, the nozzle 15, and the water supply pump 17, but the water storage device 16, When the water supply pump 17 and the nozzle 15 are arranged in order of increasing position and are connected by the water supply pipe 18a and the water supply pipe 18b to form the water supply means 19, the positions of the plurality of injection ports 29 are closed. If the positions 29a, 29b, 29c,... Are gradually increased toward the end 24 side, the air contained in the water supply pump 17 and the water supply pipes 18a, 18b is immediately discharged from the injection port 29. In addition, when stopped, air enters in reverse from the injection port 29, and the residual water from the nozzle 15, the water supply pump 17, and the water supply pipes 18 a and 18 b returns to the water storage device 16. It goes without saying.

噴射する水の勢いと遠心力にて汚れを取り除く構成により、汚れをフィルターで捕集しフィルターのメンテナンス・保守が困難な場所に設置する換気装置にも適用することができる。 The structure that removes dirt by the force of water to be sprayed and centrifugal force can be applied to a ventilation device that collects dirt with a filter and is installed in a place where it is difficult to maintain and maintain the filter.
